Step-by-step guide to create dc-on-docker on your laptop with vagrant, docker, and OpenSwitch.

Here is the 15 steps in the show:

vagrant up
apt-get install build-essential…
apt-get remove python
wget python-2.7.11 and make install
wget easy_install … | sudo python
pip install paramiko=1.16.0…
git clone https://github.com/…/ansible and make install
wget docker | sh
usermod -aG docker vagrant
ssh-keygen
git clone https://github.com/…/dc-on-docker
ansible-playbook utils/setup.py
ansible-playbook site.py
ssh netop@localhost -p 10022
show run && show ip route

I’ll re-record it next week, as this one had a glitch during the pip handling in ansible-playbook utils/setup.yaml. I figure that out that we should use easy_install pip instead of apt-get install pip as one of the play in utils/setup.yaml…

I’ll keep this asciicast in a meanwhile. :)

Happy Hacking!

See all

You can download this recording in asciicast v1 format, as a .json file.

Download

Replay in terminal

You can replay the downloaded recording in your terminal using the asciinema play command:

asciinema play 44142.json

If you don't have asciinema CLI installed then see installation instructions.

Use with stand-alone player on your website

Download asciinema player from the releases page (you only need .js and .css file), then use it like this:

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="asciinema-player.css" />
</head>
<body>
  <div id="player"></div>
  <script src="asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/44142.json',
      document.getElementById('player'),
      { cols: 81, rows: 29 }
    );
  </script>
</body>
</html>

See asciinema player quick-start guide for full usage instructions.

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/44142 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif

Check agg --help for all available options. You can change font family and size, select color theme, adjust speed and more.

See agg manual for full usage instructions.
